Trying to set up postfix on Ubuntu 14.04

I am trying to set up postfix for an smtp server for my company.

I am using this tutorial:

Everything seems to work until I get to testing it by sending an email. I have set up my A and MX recordfor the mail server (hopefully).

I am trying to use virtual_alias_maps in my /etc/postfix/ file, because everyone in the company needs a separate email address.

When I try to send an email my personal account to what will be my company email, and look it /var/mail/my_name it does not show anything. Neither will it when I use mail from mailutils

I am sorry I don’t have much information to give you all, I am trying to start over and work through it again to see if I can get it right this time.

When I first enter postfix and set up the internet site for sending, the fqnd should be or just

Thank you for reading, and any help will be appreciated. Just ask for more information and I will be happy to give it you.


@deusMach88 First ensure that fully setting-up your DNS records and don’t forget PTR ( with changing your droplet name as and ensure that ports not restricted by firewall

  • IMAP: 143
  • IMAPS: 993
  • POP3: 110
  • POP3S: 995
  • SMTP: 587

So finally check your mail server with


inet_interfaces = all

Postfix can use both of IPv4-6. So you can leave as “all”. otherwise you can specify as which is match with your needs:

inet_interfaces = all (DEFAULT)
inet_interfaces = loopback-only (Postfix version 2.2 and later)
inet_interfaces =
inet_interfaces =, [::1] (Postfix version 2.2 and later)
inet_interfaces =,


inet_protocols = ipv4
inet_protocols = all (DEFAULT)
inet_protocols = ipv6
inet_protocols = ipv4, ipv6

Hi @selcukahmet,

Thank you for the suggestion. I set this up yesterday and it works perfectly.

I was also wondering if you might know why I cannot get any messages received my the mailboxes I have set up with mailcow?

I have a look around, and I have found that some people had it that inet_interfaces was not set to all but mine is.

Any help would be appreciated.

Actually, setting up your own mail server may difficult, but not impossible. What about using mailserver suites? and here is a painless option: Mailcow Mailcow is easy to install. It gives a admin panel to configuration, adding domains, accounts, virtual mailboxes, managing spam protection etc. And also have roundcube or SOGO webmail options.

Mailcow needs

Resource mailcow (Roundcube) mailcow (SOGo)
CPU 1 GHz 1 GHz
RAM 800 MiB 1 GiB
Disk 5 GiB 5 GiB
System Type x86 or x86_64 x86_64

and also a domain, a subdomain for mailcow administration panel like and SSL

Thank you for all the links! The other person on our IT team and I will have a look over the material and see what we want to do.

Hi @hansen,

I didn’t realize there were feel control panels for email. If I cannot get postfix working, I will look into

We are a small company just starting out and I was under the impression that we did not have a lot of funds for purchasing email services.

Thank you for the information!

Hi @deusMach88

First off, just want to tell you that running your own mail server difficult. Dealing with spam, malware, security, storage and much more is a constant job. I would recommend that you don’t run your own mail server, but use one of the many providers available like or

That being said, there might be other reasons for running your own mail server, but since it seems like you’re new to Postfix, I would probably recommend using a control panel like which will take care of a lot of advanced configuration and make it much easier to manage everything. I’m guessing you want to run more than Postfix, since that’s only a SMTP - you probably want something like IMAP and perhaps even a webmail too. And on top of that, anti-spam and other measures. This is where VestaCP will give you a helping hand.
